Adidas says this is based on scans of female feet and is designed to prevent heel slip and blisters, as well as helping the shoe fit more securely. The instep is narrower in the UltraBoost 22 and sits slightly higher on the ankle. The tongue is also now more cushioned, which feels reassuringly comfortable.Īdidas Ultraboost 21, left, and Adidas Ultraboost 22 (Image credit: Jane McGuire / Future) This small change seemed to prevent the pressure and hot spots I’ve experienced on the top of my foot. There’s still the same plastic lace system as in its predecessor, but the lower laces are connected with two material loops rather than going through the plastic. I’m a UK 5 and found the shoe to fit true to size. It’s still sock-like, but I no longer feel like I’m losing the circulation in my toes after walking home from parkrun, with the bootie upper feeling like it has a lot more give. Adidas has used Primeknit+ yarn, which contains 50% recycled plastic, to create an upper that has more structure and support. The shoe definitely feels more comfortable underfoot. The result? I’ve run approximately 50 miles in the shoe, over a number of different sessions, and am impressed with the fit. Adidas says the tweaks to the upper and the fit of the UltraBoost 22 make the shoe 4% more efficient underfoot than the UltraBoost 21 for female runners. The shoe has the same extended heel as the UltraBoost 21, designed to make the shoe more comfortable for heelstrikers, and the same Linear Energy Push system on the outsole to produce a snappier toe-off. Adidas has also added more support to prevent overpronation – studies have suggested women pronate more than men because we have wider hips – with an extra plastic support rail on the outsole. However, tailoring the fit of Adidas’s most popular cushioned running shoe to women is a much bigger deal.Īdidas used an all-female design team and analysed scans from the feet of 1.2 million women to create the UltraBoost 22, which has a narrower heel, a lower instep and an S-curve heel to allow the achilles tendon to move more freely. This isn’t Adidas’s first foray into female-specific footwear: in 2016 it launched the Pureboost X, a shoe designed for female feet that had a somewhat bizarre-looking floating arch above the midsole. My running partner found that the sock upper would bunch up under the laces of her narrow feet, creating uncomfortable creases on the top of her foot.Īdidas has set out to improve things with the UltraBoost 22, changing the design of the women’s version. It wasn’t until I went for a run with another female runner that I realised I wasn’t the only one experiencing these issues. Of course, you buy a running shoe to run in it, but if I’m spending £165 on a shoe, I want to be able to wear it to the gym, or to walk the dog, or to walk around the office on the days I run to work. The shoe always felt OK while running, but the upper felt uncomfortably tight across the top of my foot the second I stopped, to the point that it would hurt. The solebox x adidas Ultra 4D will launch globally on March 17th via and all solebox locations, while the solebox x adidas Ultraboost will launch globally on March 31st via and all solebox locations.įor more sneaker news, check out the olive Bad Bunny Campus Light.Two recurring design features of the UltraBoost – which you'll find among the best Adidas running shoes for every type of runner – have been the sock-like upper and the plastic lacing system, neither of which I’ve found particularly comfortable. The bold design cue adds yet another futuristic nod to solebox’s roster of collaborations. Both understated shoes, however, make statements with their glow-in-the-dark outsoles. The shop’s name is printed onto the lateral heel, although it’s only raised on the UltraBOOST 1.0. Primeknit construction across both silhouettes favor an off white uniform the adidas Ultra 4D abandons its standard profile 3-Stripes cage. Headlined by an adidas UltraBOOST 1.0 and Ultra 4D, the newly-surfaced collaboration features a minimalistic approach. To commemorate the evolutionary design, both German institutions have teamed up on a two-pair capsule. Over the last decade, Berlin’s solebox has been delivering compelling adidas collaborations, which include an Uncaged UltraBOOST from 2016.
